Answer 2

Answer:

b) Carbon dioxide is not an organic compound.

Explanation:

• Compounds with molecules containing covalent bonded carbon and hydrogen atoms are classified as organic compounds.  

• Methane is an organic compound as it has carbon and hydrogen bond in its molecular structure. Chemical formula for methane is $CH_{4}$.

• Carbon dioxide is not an organic compound because there are no bonds of carbon and hydrogen. Chemical formula for carbon dioxide is$CO_{2}$.

• Oil is an organic compound because its chemical formula is $C_{8} H_{18}$. It has C-H covalent bond.

• Lactic acid is an organic compound with chemical formula $C_{3} H_{6} O_{3}$ which consists of C-H covalent bonds in its molecular structure.
